She had the best job in the world snogging Justin Bieber in his What Do You Mean? music video and now everyone wants to know - who is Xenia Deli?

The sexy brunette put on a raunchy display for LOVE Magazine's advent calendar to keep us in the festive spirit even after Christmas.

Xenia can be seen in the clip shaking her bum in a pair of rather big pants and a matching bra but she still looks incredibly hot.

She flicks her brunette curls about and pouts at the camera in the video, directed by Sam Faulkner.

The LA-based Sports Illustrated and Playboy model is kittenish as she dances up a high-voltage storm in the creamy satin-paneled bra and high-waisted panties.

As the enchanting seductress turns to blow a final kiss to camera for LOVE Video Advent 2015, her cascading curls almost fill the screen.

Fans allegedly watched Biebs serenade the 25-year-old Moldovan beauty on a piano after they worked together, during which he joked: "I'll be here all weekend."

Xenia Deli starred in Justin's video

According to The Sun newspaper, they were seen holding hands during a night out earlier this year and Justin shared a snap of their feet next to each other before removing it from the social media site.

His close pal Johnny Stahidi also reportedly posted a video of her fooling around on Justin's hoverboard before removing it.

We can definitely see what made Justin pick her for his video.
